" The invention is an oil burning system that mixes'comparatively cold water either fresh orsalt,-with' the-oil, then mixes the oil- "and water with air at two consecutive points, during which time the water is broken into small particles and the small particles of waterare coated with oil, and then discharged through an open pipe against an upwardly-inclined'curved baflie of special metal, and which is heated to ahigh'temperature.

It is an object of the invention to provide ameans for burning oil-'fuels which will make it possible to burn absolutely all of the oil leaving'no'residuesuch as asphaltum, tar or carbon deposits in the fire box. 7

Another object ofthe invention is to provide a burner in which-the actual ignition is deterred until chemical action, resulting from the I contact ofqthe mixture with a heated surface, has taken place.

Another object of the invention; istoipro vide a burner in which all dangers of fiare" back in lighting or relighting'arfe-eliminated; Another object of the invention is to provide an oilburning system which is so arranged so that the fuel is discharged to the fire'through the open end of a comparatively largepipejunder comparativelylow pres sure to insure against noisy operation. 7 Another" ob eet of. the mventlon ls-to proburstinto steam disrupting'the'pilcoating which produces anfatomization ofthis oil that cannotbe equaledin'a'ny other manner.'

A still furtherfobject of the-invention is to provide an oil burningisystem which has both preliminary and final combustion areas in whichfthe ingredients are changed chemically and physically in the first or incomplete combustion area and then the balance of com bustible elements completely oxidized, ignited and thoroughly burned'in the second or final combustion area.

.lVith these ends in view the invention embodies a blower in which the discharge pipe passes comparatively straight into a fire box, a triple controlvalve for controlling the proportionate amounts of air, oil and water, re-

spectively, an air connection between the blower' and said valve, other connections from the saidvalve to the said former, discharge pipe of the blower, and to air and oil supply tanks, and aburner comprising an upwardly inclined curved plate.

ventionswill appear from the following description taken in connection with the draw- 1ngs,.where1n:-1-

Figure 6 is across section through the baflle' plate looking-towardthe hub of the plate showing a semi-circular plate projecting at the dischargexopening. I r' In-the drawings we have shown our device as'it would be made wherein numeral .1 in.- dicates the blower, numeral 2 the triple con trol-valveanol numeral?) the burner. Theblower lmaybe of any suitable type ordesign}-and maybe provided with a dis.-'

.chargespipe- 4 which will extend from its dis-.

charge z-opening to the burner" 8. Another pipe 5 extends from the discharge ofthe so I , 00 .Other features and advantages of the 111- pump to the valve 2 and then passes from the valve to a fitting 6 into which it extends as shown in Figure 3. It will be noted that the lower end of the small pipe is cut as shown at the point 7 and directly below the lower end is a bafile plate 8 upon which the mixture passing through the tube will drop as it leaves the tube. It will be observed that the mixture will then be carried through the pipe 4 to the burner.

The valve 2 is made as shown in Figure 2 with an outer casing 9 and a core 10 which has a stem 11 having a handle 12 at the outer end by which it may be rotated. The outer casing is provided with bosses 13 and 14 into which the pipe 5 is screwed and other bosses 15 and 16 into which the oil and water pipes are screwed. The core 10 is provided with a web 17 which forms an upper compartment and a lower compartment, and the outer wall of the upper compartment is provided with a plurality of openings 18 which are of different sizes so that by bringing different openings in positions to correspond with the openings in the bosses l3 and 1 1 difierent amounts of air may pass through the valve; and at the same time different amounts of oil and water will be admitted-to the lower compartment through openings 19 and 20 which will correspond with openings in the bosses 15 and 16. The size of these openings will be so arranged that as the core is rotated, predetermined proportionate amounts of air, oil and water may pass through the valve and to the burner. In the design shown the oil is admitted through the pipe 21 which may be connected to a tank or any suitable means for supplying oil and the pipe 22 may be connected to a watertap or any suitable means for supplying water at atmospheric temperature. The lower end of the lower compartment of the valve into which the oil and water pass is provided with an opening 23 at the bottom which permits the oil and water to pass down through a pipe 24:, and the pipe 24 is connected to and extends into the air pipe 5, thereby forming a jet, and it will be seen that as the air passes through the pipe 5 it will draw in the oil and water and thereby break the water up into fine particles, which will become coated with oil. 7 These particles pass downwardthrough the pipe 5 and are injected against the plate 8 in the pipe 4 where any free water is broken and coated with oil and carried from this point into the burner 3.

The burner 3, which is shown in Figures 5 and 6, is provided with a hub 26 and an upwardly inclined curved plate 27. r I The pipe 4 is threaded into one end of the-hub and the other end is provided with a semi-circular plate 28 which extends outward beyond the hub and is held in the upper part ofthe opening. It will be noted that plate 28 is made of comparatively thin metal or plate and theparticles ofroil. and water with 21 11.

pass under it getting the third preparation for the first and second stages of actual combustion. It further provides a means for starting combustion quickly, such as in lighting the fire, as being thin it heats quickly and starts volatilization which in turn heats the plate 27 to the required temperature. It will be notedthat as the plate 27 is in the fire box it will become heated and as the particles of water and oil roll out and upon it they will receive their final preparation for combustion.

It will be understood that changes may be made in the construction without departing from the spirit of the invention.

The construction will be readily understood from the fore oing description. To use the device it may e set up as shown, and it will be-observed that as the blower 1 is started a current of air will pass through the pipe 4 to the burner 3 and another currentof air will pass through the pipe 5, the valve 2 and the fitting 6 to the pipe 4 and then to the burner. It will be observed that the pipe 5 is provided with long radius bends forming easy curves so that the air passing through the pipe 5 will retain a comparative constant velocity. The velocity of the air in the pipe 5 will facilitate the jet at the point 25 and at the same time cause the mixture to be injected into the pipe 4 through the fitting 6 so that it will be thoroughly broken up before it is discharged against the freely exposed plate 27. The mixture is not discharged through a jet or even a small opening, ut is permitted to flow out of the open end of the pipe so that all tendency to clog or become obstructed through carbon deposit on or in the jet or orifice will be eliminated. The large opening permits the use of a low velocity and a low pressure, thereby tending to reduce noise to a minimum. As the mixture flows out along the heated plate it receives its final preparation for combustion and undergoesinitial combustion. This action will start at the point A and from this point themixture will pass to the point 15 where complete combustion will start. This combustion will extend through the combustion chamber and burn absolutely all of the mixture leaving no residue.
